Attach Laundry Sink to Concrete Floor

I am installing a new laundry sink. It is fairly lightweight and I am concerned about someone accidentally bumping into it and damaging the drain connection. There are holes in the feet to fasten it to the floor.

I want to fasten it to the concrete floor, but do not want a big penetration into my foundation; just something strong enough to hold it firm. Would I use nails or screws? What kind? I just have a hammer and a decent corded drill. I want to be able to take it out.

Attach Laundry Sink to Concrete Floor

I'll tell you how I've done it. OK?

1) Pin the plastic legs into the sockets they slip into.
2) On the bottom of the FRONT legs pin a 1" x 3" scrap of stainless steel
(18ga is plenty; drill a pair of pilot holes at each end first)
2a) Plastic anchors into the floor (or tapcon)
3) With two more 1" x 3" scrap pieces of s/s make a pair of angle brackets (with 2 holes ea)
4) Find at least one of the studs behind your sink location (if not block)
(through screw from the faucet ledge into the angle bracket).
